Study Notes

Methods of Collecting Data

  • Primary data can be collected through direct personal investigation, indirect oral investigation, information through correspondents, telephonic interview, mailed questionnaire, and questionnaire filled by enumerators.
  • Secondary data can be collected through censuses, government departments, internet searches, libraries, electoral records, statistics, tax reports, and journals.

Health Indicators

  • Examples of mortality indicators include Infant Mortality Rate, Maternal Mortality Ratio, and Mortality From Acute Respiratory Infection In Children Under Age Five.
  • Nutritional status indicators vary in measurement and include:
    • Newborn: birth weight and head circumference, reflecting maternal nutrition status.
    • Preschool children: weight measures acute malnutrition, and height and mid-arm circumference measure chronic malnutrition.
    • Children: weight, height, head, and chest circumference are measured.
    • Adult: underweight, obesity, and anemia are reliable nutritional indicators.
    • Prevalence of low birth weight and poverty level are also indicators.
  • Environmental indicators reflect the quality of physical and biological environment and measure:
    • Proportion of population having access to safe drinking water and sanitation facilities.
    • Prevalence of communicable disease in the community.
    • Air and water pollution, radiation, noise, and exposure to toxic substance in food.

Health Care Delivery Indicators

  • These indicators reflect the equity of distribution of health resources in different parts of the country and provision of health care.
  • Examples include doctor-population ratio, doctor-nurse ratio, and population-bed ratio.

Types of Data

  • Primary data is first-hand information collected by an investigator, original, and more reliable.
  • Secondary data is second-hand information, not originally collected, and obtained from already published or unpublished sources.

Data, Indicator, and Health Indicator

  • The hierarchy of concepts in public health is: data → indicator → information → knowledge → action.
  • A health indicator is related to different types of health measures, and health system performance indicators are a type of health indicator.

Classification of Health Indicators

  • Health indicators can be classified as positive or negative, depending on whether they are associated directly or inversely with health.
  • Characteristics and criteria of indicators include:
    • Valid: effectively measures what it attempts to measure.
    • Reliable / objective: results of the measurement should be the same when performed by other people or under similar circumstances.
    • Sensitive: has the capacity to measure changes of the phenomena of interest.
    • Specific: reflects changes only of the situation/phenomenon it is related to, and not of similar or unrelated events.
    • Measurable: data should be available or easy to obtain.
